Specification of Letters Patent.

Patented May 12, 1914.

Application filed August 2E', 1912. Serial No. 717,297.

T0 all whom it may concern Be itknown that I, ANGELO PARoDi, a subject.of the King of Italy, and a resident of the city of New York, borough ofManhattan, in the county and State of vNew York, have invented a new andImproved Telegraph-Receiver, of which the following 1s a full, clear,and exact description.

This invention relates generally to telegraph receivers, and is directedto a system of coperating elements whereby the structure is adapted toactuate other elements, whereby messages may be received' through thesensations of hearing and sight.

The primary object of,the invention disclosed is the provision of atelegraph receiver adapted to record messages on a Acontinuous tape, theconstruction being characterized by a. new and improved means forfeeding the tape.

Other advantages following the use of the construction described andclaimed will appear as the description proceeds.

Reference is to be had to the accompanying drawings forming a part ofthis speciication, in which like characters of reference indicatecorresponding parts in all the views, and in which- Figure 1 is a sideview of the receiver adapted for printin telegraph symbols on acontinuous tape; Fig. 2 is a vertical sectional view thereof on the line2-2 of Fig. 3; Fig. 3 is an end view from the right of Fig. 1; Fig. 4 isa sectional view showing details of the magnetically controlled lever;while Fig. 5 is a sectional view of the pen and ink container.

lThe receiver comprises a base 1 of any suitable material and size,provided with pairs of spaced uprights 2--3 and binding posts 4,together with electro-magnets 5,

these parts being not essentially different from the parts used-intelegraph receivers at present.

Referring particularly to Fig. 4, the lever 6 is recessed as at 7 on itsunder side, and within this recess is a second lever 8, the first lever6 carrying an armature 9 and the second lever 8 having a pin 10extending upwardly therefrom and carryinga second armature 11 adjustablymounted on the pin by means of screw threads, the position of thearmature being maintained by means of a lock nut 12. These levers 6 and8 are ivotally mounted on a transversely exten ing pin 13. Theoppositely positioned uprights 2 are pro-vided with transverselyextending screws 14 carrying lock nuts 15 and forming bearings for thispin; referring particularly to Fig. 3, it will be noted that abifurcated arm 16 st-raddles the said levers 6 and 8, the particularurpose of which willbe presently set fort From this description it willbe observed that the levers 6 and 8 are movable relatively to each otherabout the pin 13, and that the levers and the bifurcated arm 16 aremovable relatively to the uprights 2.

Extending upwardly from the base of the instrument are ears 2O havingscrews 21 extendingtransversely thereof provided with lock nuts 22, andpivotally supporting the arm 23 adjacent its lower end, the lower end ofthe said arm being made up of spaced members 24; referring particularlyto Fig. 2 it will be noted that. adjacent the lower end of this arm 23is an element4 19 provided with a pocket 25 containing a helical spring26, and that the lower end of the said arm 23 is provided with ashoulder 27 having a screw 28 extending transversely thereof andengaging the said helical spring 26, whereby a certain variable,pressure may be applied to the lower end of the said arm. The upper endof vthis arm is pivotally .engaged at 29 with a link 30, the other endof the link being pivotally engaged at 31 with the upper end of thebifurcated arm 16 previously described. Extending between the lower endof the arm 23 and the adjacent end of the lever 6 is a link 32, inpivotal engagement with these .elements at 33-34,. the said link beingadjustable in length by means of a turn buckle 35, the lower end of thelink comprising spacedl sides 36, engaging the offsets 23a carried bythe arm, whereby a continuous passageway is provided between the spacedportions 24 of the arm 23, the spaced sides of the linkwill attract thethe openings and bearing against them,

whereby friction is materially reduced. Adjacent one end of the rod 38is a table 40, ontop of `which a continuously extending tape 41 isadapted to be passed, the top of the table being provided with atransversely extending bearing portion 42, the table supporting apivoted member 43 at 44, the lower end of the member being provided withan arm 45 adapted to come adjacent the said support37 when the rod 38moves in one d irection, this said pivoted member being in pivotalengagementat 46 with one end of a bifurcated link 47, the other end ofwhich pivotally engages the lower end of the bifur` cated arm 16 at 48.Since the tendency of the lever 6 is'to remain in uppermost position, asshown' in Fig. 1, when no current is flowing through the electro-magnets5, due to the pressure of the helical spring 26 acting on the screw 28carried by the arm 23 which is articulated with the lever 6, the normalposition of this table then is as shown in Fig.

1, beingadapted to travel the distancebetween the position shown inFigs. 1 and 2 when the lever 6 moves downwardly'under the niuence of themagnetic field set up by the electro-magnets; while the table 40 is beinmoved from one position to the other t e force which brings about A'themovement is communicated at the ivotal supporting point 46 which isbelow tie pivotal' point 44, so vthat the table-will move relatively tolthe tape 41 without moving it, since the pivoted member 43 is broughtre- .mote from the under side ofthe tableyon the return movement of thetable, however, the forward-,portion of this pivoted member 43 engagesthe under side of the tape which is held adjacent ythe bearing portion42, the tape being thereb fed forwardly on the'- return movement o thellevell 6 from the position shown inFig. 2 to that shown in Fig. l. j v

Referring still to Figs. l and 2 it will be noted that beneath the lever6 and lpivotally supported at to the said su port 37,'is a secpnd table51 the top 52 of w ich is curved on the arc of a circle with the saidpivotal support 50 as-acenter, the said tape 41 eX- tending overthis'curved top; the table is maintained normally in the position shownin Fig. 1 by means of a helical spring 53, certain means, however, beingprovided for bringing the table into the position shown in Fig. 2, suchmeans embodying the following elements :-Referring to Fig. 4, it will benoted that the second lever 8, which is contained within the recess 7 onthe under lside of the first lever 6, is held within the said recess byengagement with the pivoted element 54, one end of which is providedwith an adjustable screw 55 the end of which engages with a helicalspring 56 contained within a recess 57 in the end of the lever 6,pressure of the spring bringing the adjacent ends of this lever 8 andelement 54 into uppermost position, which is' shown in Fig. 1; thiselement 54 is provided with an opening 58 through which a pen 59, to bepresently described, extends, the lower end of the pen coming adjacentthe tape 41 and on top of the said curved table 52, whereby animpression or mark is left on the tape. The pen comprises the pen roper59 having an opening extending t ierethrough within `which some`absorbent material 60 is contained, the upper end of the pen beingenlarged as at 61 and containing a quantity of inked absorbent material62, these partsbeing contained within a receptacle 63 having a removablecover 64, a helical spring 65 being positioned within the receptacle andbearing against the said absorbent material in order to bringvsufiicientpressure to bear to cause the ink to flow to the point of the pen; thepen is adjustably mounted with respect to the lever 6 by screw threadedlengagement therewith, and is held in desired position thereon by meansof a lock nut 66.

Pivotally supported at 67 adjacent the curved top 52 of the table 51 isa freely movable member 68, the lower end of which rests on top of thetape passing over the table; from an inspection of Fig. 4 it will benoted that if, after the pen 59 is brought adjacent the tape, the lever8 is moved downwardly, the engagement between the projection 8? of thislever and the top of the said member 68, which engaging portions areinclme-d asvshown, will cause movement of the table 51 relatively to thepen 59, with the lower end of the member 68 in engagement with the tapeso that the tape and table are moved bodily with respect to the pen,which leaves a line of certain length on the table. It will be notedthat where the tape 41 enters the receiver from the left it passes overa rest 70, there being a gripping element 71 pivotally mounted adjacent`one end at 72 bearingl onvtop of the table, so that movement t ereoftoward the right is freely permitted, movement of the tapete the left,however, being prevented.

The method of operation of the parts shown is as `follows: With therelative arrangement shown yin Fig. 1, if a current is passed throughthe winding of the electromagnets 5 of momentary duration, that is, nolonger than to indicate a dot in the Morse up a fresh unmarked l neaththe pen. The said armatures 9 and. 11 will not move downwardlysimultane-V of contact with the end of the said pen; If, f

however, the circuit through' the electromagnets 5 is closed foi-anappreciable length of time, that is, long enough to indicate a dash inthe Morse code, the first tendency of the .magnetic field' is to bringthe lever 6 downwardly adjacentthe tape 4,1,.the tape feeding elementsmoving to the left as before and gripping the tape, the next steplbeingthe downward movement of the second lever 8 under the influence ofthe said magnetic field on the second armature 11, as shown inFig. 4,the downward movement of this second lever moving the pivoted table 51,and with it the tape, the tape being in contact with the pen, the resultbeing the formation of a line of certain length, that is, afdash on thesaid tape; when the circuit is opened the pen is brought away from thetape and the'tape feeding mechanism brings ortion of. tape beously duetothe fact that the parts possess some inertia, and also because of thesecond air gap between the said armatures independent of the air gapbetween faces of the electromagnets and the first armature. The distancethrough which the lever 6 will travel before the pen strikes the tapemay be adjusted in the usual manner by means of a set screw carried bythe'uprights 3 and provided with a lock nut 81 for retaining it in anydesired position. By means of the screw 28 andthe helical spring 26 theforce necessary to move the various parts may be closely adjusted sothat excessive force is not necessary the counterpoise 100 carried bythe upper end of the arm 16 tending to ease of operation. Finally, thearrangement of the various parts provides a printing telegraphinstrument in which the symbols of the code in` dots and dashes are setforth on the tape, the tape feeding forwardly only when required, andwithout any attention from an attendant.

Itis clear, of course, that a practical embodiment of the invention mayassume a form quite different from that herein'sliown; such change inform, however, together with the choice of'materials used in themanufacture of the structure are contemplated within the spirit andscope of the appended claims.
